OF ASTON, ENGLAND.

ACETYLENE-GASGENERATOR.

SPECIFICATION forming part of Letters Patent No. 646,316, dated-March 27, 1900.

Application filed August 25,1898. Serial No.689,520. (No model.)

This invention relates to improved appara-v tus for generating acetylene gas; and it has for its object to provide improved means for automatically feeding granulated carbid of calcium to the Water in the generating-chamber. It also has for its object to provide meansk for preventing scum or the likeA which forms on the surface of the water in the water-chamber from bubbling or splashing up againstA the top of the bell or gas-holder, said means also operating to so contract or reduce the space in the upper end of the generating- 'chamber that only a small volume of air need be displaced before the space is filled with gas. Finally, it has for its object to improve and simplify the construction and render more efficient the operation of this class of generators generally. Y

To these ends myinvention consists in the features and in the construction, combination, and arrangement of parts vhereinafter described, and particularly pointedout in the claims following the description, reference being had to the accompanying drawings, forming a part'of this specification, wherein- Figure l is a vertical central sectional view, partly in elevation, of my improved apparatus; and Fig. 2 is a View in side elevation thereof, taken at a right angle to Fig. l.

The gas-holder of the apparatus consists, essentially, of a double-walled vessel A A2, between the two walls of which is contained water in which the bell or gas-holder b is sealed and is free to rise and fall. The vessel for containing the water in which the carbid ot' calcium is immersed consists of a bucket'ct, provided with a handle ct and removably seated in the double-Walled vessel A A2. In the upper open end of the bucket is arranged a hollow displacer i, provided on its under side with a conical recess or chamber 2, open at both its top and bottom, as shown in Fig. 1 of the drawings. The displacer c' may be supported in any suitable manner immediately above the level of the water in the bucket a, said displacer in the present instance being shown as resting on an annular shoulder fis, Xed to the interior of the bucket, and operates to prevent scum or the like which forms on the surface of the waterin the bucket from bubbling or splashing up against the top of the bell or gas-holder b and at the same time so contracts or fills the space that only a small volume of air need be displaced before the space is filled with gas. Fitted in the top of the bell or gas-holder is a pipe b2, forming an exit for the generated gas from said bell or gasholder, and fitted on the upper end of said pipe is a globe or hollow' sphere Zo, in the bottom of which are fixed two nipples 7a2 7.52, over which are fitted the -lower ends of flexible tubes f.

The letters c e indicate the carbid-containing vessels, each preferably comprising a double conoidal-shaped hollow vessel provided at its opposite ends with circumferentiallygrooved wheels e2 e2, that are adapted to travel on rails Z Z, supported above the gas holder and generator. The rails Z Z may be supported above the generator by any suitable or preferred means5but in the drawings I have shown said rails formed integrally with depending bracket-arms Z', that are bolted at their lower ends to standards cZ, fitted in sockets d', attached to the sides of the vessel A. Said rails are also shown as bein g formed with upwardly-extendin g bracket-arms Z2, connected together at their upper ends by a crossbrace Z3. The means shown for supporting the rails form no part of the present invention, and any means suitable for the purpose may be employed.- Depending from the bottom of each of the carbid-containing vessels is a tapered pipees, said pipes at their lower ends being fitted in the upper ends of the flexible tubes ff and pivotally connected together by pivoted arms or extensions e6. The iieXible tu bes f f are inclosed in and protected by the globular metallic casing Zc, as shown, and the ends of the pipes e3 Work in slots 7c in said casing. Each of the carbid-containing vessels e is provided with a funnel-shaped filling-aperture, through which the granular carbid of calcium may be introduced, and is closed by a screw-plug e. The gas is conducted from the bell or gas-holder by a pipe c. Valves Zt are arranged in the pipes c3 and IOO a eliic b2, by means of which the operation of theA parts may be controlled.

The operation of my improved apparatus is as follows: As the gas passes out through the pipe c the bell or gas-holder descends, said descent being accompanied by the descent of the delivery ends of the pipes e3 and the globular casing 7c, thus straightening out the iiexible tubes fand permitting the granular carbid of calcium to feed down into the vessel a, whereupon an increased supply of gas is generated and the bell or gas-holder again rises, carrying with it the parts to the position shown in dotted lines in Fig. l of the drawings, and thereby shutting oif the feed of the carbid until the bell or gas-holder again descends. The feed of the carbid will be thus automatically regulated and controlled.

Having described my invention, what I claim isl. In an acetylene-gas generator, the combination with a gas-generating chamber, of a tilting carbid-container arranged above the gas-generatin g chamber, a discharge-pipe connected with thefcarbid-container, a verticallymovable gas-holder, and means actuated by the rising-and-falling movement of the gasholder for tilting the carbid-container to move the discharge-pipe toward and from a perpendicular position and alternately feed the carbid to the gas generating chamber by gravity and cut off such feed, substantially as described.

2. In an acetylene-gas generator, the conibination with a gas-generating chamber, of a tilting carbid-container arranged above the gas'- generating chamber, a rigid dischargepipe connected with the carbid-container, a flexible tube leading from said discharge-pipe and discharging into the generatingchamber, a vertically-movable gas-holder, and means actuated by the rising-and-falling movement of the gas-holder for tilting the carbid-container to move the discharge-pi pe toward and from a perpendicular position and alternately feed the carbid to the gas-generating chamber by gravity and cut off said feed, substan tially as described.

3. In an acetylene-gas generator, the combination with a gas-generating chamber, of two tilting carbid-containers arranged above the gas-generatin g chamber,a rigid dischargepipe connected with each of said containers, flexible tubes leading from said dischargepipes into the gas-generating chamber, a vertically-movable gas-holder, and means actuated by the rising-and-falling movement of the gas-holder for tilting the carbid-containers to move the discharge-pipes toward and from a perpendicular position and alternately feed the carbid to the gas-generating chamber by gravity and cut off such feed, substantially as described.

4:. In an acetylene-gas generator, the combinat-ion with a gas-generating chamber, of two tilting and rolling carbid-containers arranged above the gas-generating chamber and arranged to move toward and from each other on suitable guideways, a rigid discharge-pipe connected with each of said containers, flexible tubes leading from said discharge-pipes into the gas-generating chamber, means pivotally connecting together the ends of said discharge-pipes, a vertically-movable gasholder, and means actuated by the rising-andfalling movement of the gas-holder for tilting the carbidfoontainers to move the dischargepipes toward and from a perpendicular position, substantially as described and for the purpose specified.

5. In an acetylene-gas generator, the coinbination with a gas-generating chamber, of parallel rails fixed above said chamber, two tilting and rolling carbid-containers provided with wheels arranged to travel on said rails, a rigid discharge-pipe connected with each of said containers, flexible tubes leading from said discharge-pipes into the gas-generating chamber, arms pivotally connected to the ends,

of the discharge-pipes and to each other, a slotted globular casing inclosing the said flexible tubes and the ends of the discharge-pipes, a vertically-movable gas-holder, and means connecting said holder and globular casing, substantially as described and for the purpose specified.

6. In an acetylene-gas generator, the combination with a gas-generating cha mbcr and a bell or gas-holder, of a hollow displacer supported above the water-level in the generating-chamber and provided centrally with a conical recess or chamber open at both its upper and lower end, substantially as described and for the purpose specified.

In testimony whereof I hereunto affix my signature in presence of two witnesses.
